Summary
The top of the iO line for users who want AI-powered brushing feedback, a full-color display, and app connectivity. CNET notes the iO series has five brush modes — more than most competitors — and the 9 adds the most comprehensive smart tracking.
Wirecutter's top pick for nearly a decade and Reddit's go-to recommendation. Delivers everything you need — timer, pressure sensor, affordable replacement heads — at a price that makes premium brushes hard to justify.
Pros
- AI-powered brushing map tracks coverage across all tooth zones
- Full-color interactive display shows mode and battery
- Five cleaning modes including whitening and super sensitive
- Magnetic drive system for smooth, quiet operation
- Premium travel case included
- Built-in 2-minute brushing timer and pressure sensor
- Affordable replacement heads (~$14 for a pack of three)
- Compact, travel-friendly charger
- Oscillating round head cleans between teeth effectively
- Proven durability — users report 7+ years of use
Cons
- Expensive — hard to justify vs. Pro 1000 for cleaning performance alone
- Battery life still only ~2 weeks
- App required to unlock full value of smart features
- iO replacement heads are costly at scale
- Many users find smart features gimmicky after initial novelty
- No Bluetooth or app connectivity
- Only one cleaning mode
- No travel case included
- Charger is proprietary, not USB
Our take
Most people don't need this, and Reddit will tell you the Pro 1000 cleans just as well. But if you're a data-driven person who actually wants to improve brushing technique, the iO9's AI coaching is the most capable Oral-B has ever built.
This is the one. If you buy the Pro 1000 and use it consistently, you will not need anything else. The fact that a CNET editor replaced a stolen $200 brush with this $50 one and never looked back says everything.
